NEMIX RAM 16GB DDR3 1866MHz CL13 1.35V 204-Pin SODIMM iMac Late 2015 27" memory upgrade

16GB DDR3 SODIMM for iMac Late 2015

This 16 GB DDR3 1866 MHz module is built specifically for the Apple iMac Late 2015 27-inch Retina model 17,1. It targets owners who need a single high-density stick to reach the platform maximum without mixing densities. The 204-pin SO-DIMM form factor and 1.35 V operation match the factory specification exactly.

CL13 timing and 2Rx8 organisation

The module runs at CAS latency 13 with a dual-rank 2Rx8 layout, which the iMac memory controller expects for stable operation at PC3-14900 speed. Major-brand Samsung, Micron or Hynix ICs are used, and every stick is stress-tested under load before shipping. No extra software or heat spreader is included because the system manages thermals internally.

Unbuffered non-ECC 204-pin build

The bare green PCB carries no heat spreader, keeping the profile thin enough for the tight iMac SO-DIMM slot. Gold-edge contacts on the 204-pin connector resist oxidation during the upgrade process. Non-ECC unbuffered design means the module works only in consumer Macs that do not require error-correcting or registered memory.
